Serial No. 149,840.

as clearly shown in Fig. l, and in theopposite side' walls of the furnace chamber a are apertures ar* and a, the apertures a5 which are. inthe right side wa'l'l of the furnace chamber being higher than the aper-l tures o* in the left sidel ofsaid chamber, in the construction shown, and passedthroi'i'gh the apertures a* and a?, three of which are shown, are conveyer tubes b and the vertical diniensions of the aperturesaf* andy a5 are of greater dimensions than the diam-- eters of the conveyer tubes b, whereby. said conveyer tubes may'1 be tilted"y and'. the inclination thereof increased ou de 7 creased' as may be desired. andi mounted on said` conveyer tubes on the outer' faces of. the side walls of the furnace chamber in which the apertures' a* and a5 are formed, are plates b2 by which said` apertures a* and a are closed', andK these plates are provided withvertically' ar,- ranged slots b3 through which screw-s b* or other securing devices are passedfto' hold said plates in position, andiby means of this construction the saidplatesare made vertically movable with the conveyer tubes.

'The conveyer tubes b communicate at their higher' ends with aV supply; hopper 0 and at their lower endswith a receiver boxf or casing d, andv said supply hopper andl receiver box are provided with stuing boxes c2 and (Z2, and th'esaidzconveyer tubes'y are also provided at their higher ends, in the construction shown, and inwardly ofthe supply hopper c with belt pulleys e.

The supply hopper c andthe receiverbox-` (l are mounted in a frame f which,` in the' construction shown, is oblongy and rectan-v gular in form and coinpriscsend members f2 and f3 and parallel side members f* connect; ed centrally by vertical side members f5, and connected with the partsf of the frame and at one side ofs'aidframe is ak stub shaft g and at the other side' thereof a driven shaft g2, and mounted on'tlie shafts g and g2 are Suspenders gaby' which the frame f maybe suspended from' any suitable support, not shown.

The receiver box l is provided at one end with a discharge spout d", and passing throughthe bottomofy said receiver box is a conveyer shaft (Z3 provided within saidV box with the usual spiral conveyer (Z4, and said shaft is provided with bearings d in the bottom side members f4 of the frame f, and one end thereof projects at one side of said frame and is provided with a pulley d".

Mounted in the end portion of vthe frame f in which the supply hopper c is mounted and at the opposite sides of said hopper are drive shafts 71, and e', and these shafts are provided at one end with pulleys h2 and 2, and the driven shaft g2 is provided with pulleys g1 and g5, and mounted on the pulleys 11,2 and g5 is a belt y', and mounted on the pulleys 2 and g4 is a belt jz, and the ydriven shaft g2 is also provided with a pulley 96, and the pulley d on the conveyer shaft Z3 is geared in connection with the pulley g by a belt js.

The shafts 71, and z' are provided with worms h3 and i3, and mounted below said shafts and transversely thereof and at the opposite sides of the supply hopper c are shafts lo and m on which are mounted worm gears k2 and m2 which mesh with the worms k3 and 3, and the shafts le, three of which are employed, are provided with pulleys 7c3 geared in connection with the pulleys Ie on the conveyer tubes Y; by belts 7:4, and the shafts mare provided with pulleys m3.

In the higher ends of the conveyer tubes b are `placed conveyer screws or spirals fn, having shafts n2 which pass through the supply hopper o and are provided at their outer ends with pulleys n3, and the pulleys n3 and m3 on the shafts m are geared in connection by belts n4.

The conveyer Z3-d4 is mounted in the bottom of the receiver box al and the top of said box 'is provided with a discharge pipe 6F, and said receiver box is also provided inthe outer side thereof with a transparent window or panel device da through which the contents, or the interior 'of said receiver box may be observed by the operator.

With the construction hereinbefore described power is applied, in the operation of the apparatus, to the shafts h and z', in any desired manner, and by means of the gearing connectingsaid shafts with the conveyer tubes said tubes are rotated as will be readily understood, and in this operation the conveyers '1t-#a2 are also lrotated as is also the conveyer cl3-d4, and the operation will be readily understood from the foregoing description when taken in connection with the accompanying drawing and the following statement thereof.

Suppose it be desired to treat barium 4sulfate and coal to produce carbon monoxid gas and barium sulfid,`the process of operation will be as follows z- The barium sulfate andcoal in a finely divided powdered, or granulated form, are deposited in the supply hopper c and said hopper is illed with said material, as indicated at 0 in Fig. 1 to a point above the ends of the conveyer tubes b that com- The heat is then applied in the furnace chamber a3 by means of a gas burner, oil burner, or by any other suitable means located in the fire chamber a2, and the temperatureof said furnace chamber is raised to a point approximately 1800O F., and this operation forces the air, to a large extent, out of the conveyer tubes I) and out of the receiver box d through the pipe i7 and the discharge spout Z2 of saidbox, after which the mechanical parts of the apparatus are put in operation and the material in the supply hopper c is fed through the conveyer tubes Z) and -discharged into the receiver boxed. Inthis operation, carbon monoxid gas and barium sulfid are formed, and said products are separated by gravity in the receiver box d, and the barium sulfid collects in the bottom of the receiver box4 as shown at @2in Fig. 1, while-thecarbon monoxid gas passes -oif through the pipe di and is received in any suitable receptacle provided therefor, and from which it may be taken andused for any desired purpose.

At the beginning of this operation, the

pipe @Z7 is left open as is also the dischargev spout d2 and a small amount of the carbon monoxid gas and barium sulfid may be lost. until the air is fully expelled from the conveyer tubes b and the receiver box al and at the end of this time, or when the apparatus is fully in operation, the process will be, as

above described, and will be continuous as will be readily understood. i y

My invention is not limited to the method of excluding or discharging the air from the conveyer tubes b and receiver box d by the operation of the apparatus itself, as,`

herein described, and other ormechanical means may be provided for accomplishingy this result as desired.`

From the foregoing description, it willbe seen that the frame f withthe movable` paratus, including the furnace may be" mounted to tilt in a vertical plane, if ,desired, and various other changes in and modifications of the construction hereinv shown and described may be made, within the scope of the appended claims, without strontium sullid, my invention is notilimited to the treatment of said material for such purpose and other materials may betreated: in a similar manner for a, similar purpose, as will. be readily understood;` and in` the treatment of the barium sulfate and coal, as

herein described, to produce carbon monoxid gas and bariumy sulfid, the proportionate parts of the barium sulfate and coal ein,- ployed are in the proportion of Q33 pounds of the former to 50 pounds of the latter, these being the proper molecular proportions in order to produce the` desired results,l and this rule must be followed in the treatment of any other material.

It will also be understood that` the operi tion of passing the material through the conveyer tubes I), in theoperation ofthe ap paratus as herein described, is etl'ected largely by gravity and the rotation ofi said conveyer tubes, the conveyers '1i-#n2 serving principally to start or initiate the passage of material through said tubes, and in the accompanying drawing the conveyers a-Jng are shown as passing only to a small extent into the conveyer tubes, but my invention is also not limited to this paticular construction.

I have also shown and described herein three of the conveyer tubes b and the necessary mechanical arrangement in connection therewith, but it will be understood that my invention is not limited to any particular number of said tubes, any desired number of which may be employed, and the conveyer may consist of a single tube, if desired, in which case the other mechanical parts would be limited to correspond therewith, and in the appended claims the term or terms conveyer or conveyer tube when used in the singular must be understood as meaning or including one or more of said conveyers or conveyer tubes.
